Zettabyte, a global AI computing company, today announced the general availability of Model-as-a-Service on zCLOUD, its GPU cloud. Teams can efficiently call open-source models through API on Zettabyte’s NVIDIA H100, H200, B200, and B300 GPUs. Model-as-a-Service hosts popular open-weight and open-source models, ready to call through an API and run on Zettabyte’s GPUs. Teams that want raw capacity can still rent GPUs on zCLOUD and run their own models. Model-as-a-Service on zCLOUD is generally available today at www.zettabytecloud.com.
